IMPRQVEWIENT IN PAPER-COLLAR MACHINES.

Specification forming part of Letters Patent No. 122,444, dated January 2,1872.

To all 'whom it may concern:

Beit known thatl, CHARLES H. DENIsoN, of Vthe city, county, and State of New York,

\ have invented a new and useful Improved Paper-Collar Machine 5 and I do hereby declare that the following is a full, clear, and exact description thereof', reference being had to the accompanyingildrawing making a part of this4 speciiication, and to the letters of reference marked thereon, in which- Figure l is a plan view of my invention.'A Fig. 2 is a frontview of the same.

Fig. 9 is a side view of a portion of the feeding-chain. Fig. l() isv a plan view of the same. Fig. ll is a rear view of the punclr ing apparatus; and Fig. l2 is avertical section through the punchplrm ger at line U.

My invention relates to a machine for manufacturing paper collars, or collars composed of paper and cloth combined; and it consists in the construction and arrangement of the same, in Which a folding-knife is located `beneath the embossing-plunger and upon the bed of the machine, the knife being attached to a movable piece which is slotted to receive setscrews, so that the piece with the knife may be adjustable to any desired position. The knife-counter is a separate piece, and is placed in a recess made in the embossing-plate to receive it, so that the counter may be quickly and easily changed to conform to any particular form of knife which may be being used. The feed-chain is made in small pieces hinged together', and has at certain intervals piecesl attached thereto, having a slot made through each, into which is fitted to slide freely a tongue, to one end of which is attached one end of an elastic spring or rubber, the other end of said rubber being attached to the flat part of the chain. The feed-cl1ain is carried over two rollers, one of them (the feed-roller) being actuand a recess is made in the table or platform, so that one of the feed-chains may be moved laterally upon the feed-rollers, so as to bring the chains nearer together or further apart, according to the length of the blank collars being passed through the machine. i

Arranged upon the same frame, and to the rear ofthe embossing and folding apparatus, is a punching apparatus, consisting of three punches with their dies, the two end punches being arranged upon a plunger in ways or guides, so that they may be moved longitudinally along the plunger; andthese two end punches move vertically in guides having the dies made thereon, said dies or their plates resting upon the bed of the machine, and secured thereto by set-screws passing up through the bed of the machine into the die-plates and arranged in this way the two end punches and dies may, by loosening the set-screw of each, be moved either nearer together or further apart to suit the length of collar being operated upon.v The middle punch passes up through a transverse slot in the plunger, and is secured thereto in such manner that, by loosening a nut upon its upper end, it may be moved a little eitherway transversely with reference to the plunger, and the die is arranged upon the bed so that by loosening the set-screw beneath it may be moved to correspond with the position of its punch. A roller or shaft, e2, isplaced at the end of the machine, upon which the feed-chains el are carried, which carry the collar from the embossing and folding apparatus tothe punchers, saidchains being also placed upon and actuated by the same feed-roller that actuates the other chains that carry the collars to the einbosser and'folder.

That others skilled in the art may be able to make and use my invention, I will proceed to describe the same both in construction and operation.

In the drawing, B represents a frame having the uprights A and a bed, L', between. A shaft, E has its bearings in these uprights at A3, and upon this shaft are arranged the ecwww.. u .U

tions a2 thereon, is attached to the lower side of the plunger by inserting the said projections in the dovetailed recesses ct. To this plate is attached the embossing-plate G having the die f2 attached around the edge, and a longitudinal recess or trough is made in the embossing-plate, into which is inserted the piece j' having the curved channel f1 made therein,

which forms a counter-die for the folding-knife, which will be hereinafter explained. L represents a plate having a recess, l1, at each end, along which pass the feeding-chains, and the main part of said plate is recessed or made thinner than the ends 5 and a thin plate, Z2, curved up on one edge, and having a curved knife, l, attached thereto, is secured to the plate L by set-screws passing through slots in the plate l2 and into the plate L. Back oi.' the folding-knife l and in the recessed plate L the counter for the embossing-tool is placed, and, if the counter is iitted so as to occupyV all the space between the knife and the iiange o2, it will retain its place properly. A recess is made in the bed of the machine, into which the plateL is placed so that the knife will be directly beneath its counter f1 in the emboss- -ing-plate. A feed-roller having -lo11g'itu(.linal grooves therein, as shown at h, has its bearings in the i'ranielB, and is caused to make intermittent rotary movements by the toothed wheel g and a ratchet within it, which wheel is operated by the toothed segment d', to which is attached one end oi' the rod d, the other end being attached to the wheel K or to a crank-pin upon the shaft E. The feedingchain is made ot' a-series of small plates, as shown in Figs. 8 and 9, wliich are jointed or hinged together at s; these joints being all upon one side oi' the chain, while the other side presents a general even or fiat surface. To the upper or sinooth'side ofthe cha-in are attached the studs s, each having a slot extendingeir tirely through it longitudinally with reference to the'chain, and a tongue, t', is inserted in this slot, said tongue extending through and having a pin, t2, placed in the -tongue at the rear of the stud, so that after the tongue has been inserted and the pin secured in the tongue the latter cannot be withdrawn from the stud; and a piece of elastic is secured to the iront end of the tongue at the lower part, the other end of the elastic being secured to the chain at t, or at any convenient distance from the tongue; and this elastic lies nearly iiat upon the chain, and is of such length that when so secured the tongue is drawn out by the elastic until the small pin t2 stops against the rear edge ot' the stud. rlhese endless chains run upon the feed-rollers h and also upon the auxiliary feed-rollers h at the other end of the table U, the joints or hinges s dropping into the grooves in the feed-rollers It, said rollers, as they revolve, causing the chains to move intermittently along the surface oi' the table C. A recess, D, is made along the table C, so that it a long collar is to be operated upon the outer chain 6 may be in the position shown in Fig. l, and if a shorter is to be made the chain 6 may be slipped along the feedrolls h nearer to the middle ot' the table. To the uprights A upon the rear side of the plunger is secured a bar, H, to which are pivoted the two levers b, the long arm of each resting at the end upon the piece o, which is attached to the plunger G by the set-screw t, and the short arm of each resting upon a small rod, b', which passes through a guide, t', attached to the plunger G. To the lower ends of these rods/b is attached a bar, I1, having the gauges 0 thereon. Behind the embossing and folding apparatus, and arranged upon the same fra-me B, is the punching apparatus having the table N between, and in order that the collars may pass through the whole machine easily the tables C and N andthe top of the lower plate ot': the embossing and folding apparatus, together with the tops of the dies of the punching apparatus, are lall upon nearly the same level or plane.

erated in upright guide-ways by means of ecy centrics upon the revolving shaft M, in a similar manner to the other plunger, G, and upon the top of the plunger l are made the ways o', exten ding longitudinally along the plunger, and in these ways is a plate, o", titted so as to slide freely therein, as shown in Figs. ll and'l2. The two end punches, having a screwthread made upon the extreme upper end, pass up through this plate, and a nut, af, is turned on at the upper end. Another plate, '03, is placed on the punch just belowthe plun ger, with a nut beneath said plate, or a collar upon the punch-rod at this point, so that the plunger could bear upon it as it made its downward movement, would answer the purpose. A slot, y', shown in Fig. l2, is made longitudinally in the plunger l", sothat the punchrod may be moved either way along the plunger, when necessary, and the nuts al and u2 may remain suiiiciently loose, even while in use, that the plate o may iind its own position directly over the punch-guide k1. lhe dicplates Q, for the two end punches, are made all in one piece with the guide k1, both being connected by the crook 7c3, and the die-plates, .with their guides and punches, are all iirmly secured to the bed S by set-screws q, passing up through the bed into the die-plates. lhe two end punches are each set with the crook 7c3, extending out toward the end of the bedplate, so that the collars, as they are punched,

may be carried through and pass oi'' the end ot' the machine. 'lhe plunger has a transverse slot, z, made therein at the middle, and the middle punch has a screw-thread at the top, and is secured in any desired position by turning onthe nut u1 down iirmly against the plunger, the punch having a shoulder thereon,

' attached to each upright'Al.

i 122,444A n 3 which is thus brought up against the plunger, holding the punch in its position. The dieplate for this middle punch is secured to the bed-plate by the set-screw in the same manner as the others are secured; butin adjusting the middle punch the punch itself and its die-plate have'to be adjusted'separately, either adjusting the punch iirst in the desired position, and then adjusting the die-plate to it, or vice versa. A cam, M, is placed upon the shait M, and an upright lever, NI, is attached to the inside of one of the uprights A4, the lower end of which lever is pivoted to a short horizontal lever, O', one end of which is pivoted at 0, and to the other end is attached an upright4 guide-rod, h, working in a guide, a, There are two longitudinal levers, O7 and also two guiderods, 1L, one of each attached to each upright `A4, and a horizontal bar, m., is attached'to the two guide-rods h", and to said bar m are se-l cured vertical rods m', the lower ends of which, when down, strike the top of the table. To cause the shaftsE and M to revolve, power is applied by the pulley F3,shaft E, and toothed wheels E and Ef.

The operation of my invention is as follows: The blank collars are laid upon the table G,

and, as the chains e and ef" pass along beneath them, the collars -are caught and moved along by the tongues t coming against their edges; and as the plunger Gr rises the piece o upon the plunger raises the long arms of the levers b,- which causes the short arms to force down the rods b. rlhis operation pushes down the gauges b", so that soon after the plunger begins to make its downward movement the gauges strike down upon the embossing-bed. The tongue t brings the collar up against the gauge, and if there be any irregularity in the placement of the studs `s" upon the chain; or

if there are diiferent collars of diiferent Widths being operated upon at different times, the elastic u stretches a little, the tongue pressing the collar against the gauges and springing back to accommodate the width of collar lying between the tongue and the gauge, the chain moving in the direction of the arrow in Fig. 9. rIhis adjustment of the carrier, which moves the Vcollar to the folding knife and embosser, as also to the punches, may be as well accomplished by means of a metallic spring placed either behind the movable carrier or in other convenient juxtaposition with the carrier, so that said movable carrier may attain the same nicety of movement .in adjusting itself to the collars as they are carried up to the gauges. As the plunger continues its downward movement the rods bare forced up again as the long arm of the levers b drop down, and when the plungerl has completed its stroke, and has embossed and folded or creased the collar, as it commences its upward movement, the spring I presses against ,the rods b', retaining them in their elevated position, and the collar is free to move on, and is carried along by the tongue i until it presses down over the feed-roller h. The

movement of the collar has thus far been accomplishedlby the cha-ins upon the folding and embossing-table; but the tongues c on the chains of the punching-table N, which are car! ried by the same feed-roller, take the collar as soon as the other chains leave it and carry it along to the punches. As the point of the cam M upon the punch-shaft M passes the upper crooked end of the upright rod N it is raised by the cam, and is quickly dropped again; and when the said rod is raised, the lever O', bar m, and rods m are all raised, leaving the collar free to be carried by the chain past the punches and off the end of the machine. When the rods m are down in coning-chains passing along the table N; and

vwhen the cam M/ raises the lever and rods m',

then the collar is carried oif the machine by the said chains after being punched. VVhenever it is desirable to use knives having different curves for folding or creasing the collar, y

the plate b2 may be detached from the bed by turning out the screws n3 and attaching an# oth er of a different curve; and also taking out the counter j' and substituting another corresponding with the curve ofthe knife to be used. When collars of different sizes are to be made different plates L are used, each plate for each size of collar being arranged with the recesses l', of the proper distance from each other, in order that the feeding-chains will be guided so asto move against the collar, in carrying it to the embosser and folder, at each end. The guide C is attached to the frame A1 by screws C, in an inclined position with referenceto the direction of the feeding-chains, and the auxiliary chain 6 is placed between the two main chains e, to carry one end of the collar until it nearly reaches the embosser, when the guide U will have moved the collar over upon the chain e just outside the chain e, and the chain 6', being carried upon an auxiliary roller placed beneaththe table U, and in front of the embossing-bed, does not reach the Y embosser, the chains e carrying the collar beneath the embosser and upon the tableN into a position to be carried by the chains e -to the punches. i

Having thus described my invention, .what I claim as new, and desire to secure by Letters Patent, is

l. The feed-chain having the movable or elastic carriers vt arranged thereon so as to give a proper adjustment to the collars as they are brought up to the gauges, substantially as described.

2. I claim the knife Z attached to the plate b2, which is adjustable upon the bed by means of the set-screw 01,3,si'1bstantially as described.

3. I claim the knife-counter j', secured in placev in the recess in the block G, substantially as `and for the purpose described.

et. I claim the feed-chain e', made movable cured so as to be movable in the plunger P, substantially as set forth.

7. I claim the combination of the plunger G, the levers b pivoted to the bar H, spring I, rods b", and gauges b, substantially as and for the purpose set forth.
